Overview

A quintessential 1970s 'Space Age' timepiece featuring a robust Swiss automatic movement and a distinctive tonneau-shaped stainless steel case.

Story

In 1969, Tissot launched the Sideral as the world's first fiberglass watch, a revolutionary move that aimed to capture the global excitement of the Apollo moon landings.

Maker / Origin

Founded in 1853 by the father-son duo Charles-Félicien and Charles-Émile Tissot, the company has a legacy of 'firsts,' including the first mass-produced pocket watch and the first anti-magnetic watch.

Condition & Value

The watch shows significant 'honest wear,' including heavy scratching on the acrylic crystal and the steel case/bracelet. The dial appears remarkably well-preserved, which is vital for value.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues
